These screen frames have each a side memher, as designated by thenun'ierals' 2i and 2 5 to 3 members 26 and 2'? bottom members '28 and29, and bindings 30 and 31 on the overlapping edges of the screensections.

The side members are provided with portions bent to interlock withmembers 32 secured to the side members of the window frame and extendingin a vertical direction.

Figure 7 shows the side frame member 24: and Figure Sthe' side framemember 25. T he side frame members have formed on the edges of the bodyportions 48 opposite to the bookedmember e7 flanges 49 extending atright angles to the body portion and formed by rebendln the sheet metalupon itself, then in parallelism to the body portion into abutment withthe shoulders 50 provided by the hook members, and thence transverselyin parallelism with the body member again to form clamping members orshields 51 which then extend in parallelism to the flanges l9 providinga lip 52 overlapping the edges of the flanges. 7

The two side frame members differ from each other merely in the detailof the extent of the flange 49 and the associated portion of theclamping member 51, as will be clearly seen by an observance of Figures7 and 8 and'the purpose of this arrangement will be apparent by anexamination of Figure 2 of the drawings. I The binding of theoverlapping edges of the screen sections is illustrated in Figure 2 ofthedrawings and in an enlarged detail in Figures-9 and 10. The bindings'30 and 31 are both constructed of strips of sheet metal folded uponthemselves providing a body portion 53 having a flange extendinglaterally therefrom at one edge, as shown at 54, and

a clamping portion 55 extending from the other edge in parallelismwiththebody porflange, as at 56.

- The portion 56 has a head 57 formed thereon in the construction asshown in Figure 9 of the drawings'and this head or flange 57 constitutesa'baffledesig'ned to rest against the screen material; of the "OPPOSItQscreen section. The metal .of-the flange 54, and of-the r member 55 areboth turned "in, as clearly shown inFigure 9 of the drawings to concealthe raw edges of thematerial.

The construction as illustrated in, Figure 10' shows a similarbead orflange 58 conthe'twoscreen section's. The 'two baflies 57 and 58constitute a double guard against the passage of flies or other insectsfrom the out structed at the meeting of the body portion 53 and theclamping member 55. This m'ember 58 also constitutes a 'baflle, toprevent the ingress of insects into the space 59 between members,theviewbeing taken on line 1111 of Figure 2 of the drawings,and illustratesthe manner in which this baflie member is cut away, as at 60, toaccommodate the same to the portions lifi of' the top and bottom-framemembers of the section 18;

, The screen construction herein'describ'ed a single strip of sheetmaterial so bent upon itselfas to give rigidity and strength withoutresorting to the provision of tubular beads and other similardevices forstrengthening the construction thereof, all of the partsof eachof theframe members being formed by bendings made in the. material of a singlestrip of sheet metal. -A sturdy connection '00 1 between the relativelyslidable screen sections has thus been provided which lends strength tothe con action and facilitates the sliding of one section upon the otherto adjust the screen to'the size of thewindow to be fitted; These screensectlons are also provlded with an interlocking or lnterengaglngconnection with slideways mounted in the window frame ofv a characterthat will prevent the accidental collapsing of the screen sections andtheir. dropping out of the window to the ground below.

The construction also lends itself to ad j us tment of the screensections to deformities in ,the' windo-w frame due to settling of thebuilding or otherwise and provides an insect tight connectionbetweenthe, screen sections and between the screen sections and the surroundingwindow frame, It will be understood,
